Great idea Roman! Will you be doing another run in the Autumn? Hope so as just right now funds are pretty low.

Wow, I'm really interested by this one, as it would be the perfect DIY project to start a Buchla modular.

I'd like to see the BOM though to check if there are some really hard to find parts.

What are the power requirements for Buchla modules?

Again, great project! :nana:

Two questions before i might ruin myself by jumping in ... :hihi:

1. how many and which vactrols are used?

2. i heard about buchla using 1.2V/Okt in some synths.
What is the standard for levels in (this) Easel (Pitch, Audio, Trigger, Gate).

(Sorry for this newby to Buchla question :oops: ).

(Sorry for this newby to Buchla question :oops: ).
it uses 12 single VTL5C3 vactrols
CVs are 0-13.5V
pulses are 10V spikes with 5V sustain gates
oscillators are around 3.5V/oct, but after changing one resistor per oscillator it may be calibrated to any scale

While looking for uA726hc's I found some listed as can8 and some listed as can10. Some of them were marked as fsc.

I wasn't able to find info on what these indicate. What is the difference between can10 and 8? What is fsc?
